Solution Overview

Problem

Razor manufacturers face difficulties in clearly communicating the performance benefits of shaving razors, such as lubrication and moisturization, to consumers, as existing demonstration methods cannot effectively illustrate the shaving surfaces and components during a shaving stroke, hiding the blades and components from view.

Innovation Solution

A method involving a transparent surface for demonstrating shaving razors, where the shaving surface of the razor is illustrated through a second transparent surface, allowing the razor to move and optionally releasing substances in front of or behind the blades, enabling clear visualization of the components and their benefits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If traditional opaque demonstration surfaces are used, then the demonstration setup is simple, but the shaving surface and blade components are hidden from view, making it impossible to visualize performance benefits

Engineering Contradiction:
Improvevisibility of shaving surface and componentsVSAvoiddemonstration apparatus structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies transparency as a visual property change to the demonstration surface. By using a transparent surface instead of an opaque one, the shaving surface and blade components become visible through the demonstration apparatus, allowing consumers to observe lubrication and moisturization performance without complicating the overall device structure

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent creates a visual copy or representation of the shaving process by allowing observation through the transparent surface. The demonstration apparatus replicates the actual shaving action with visible components, enabling consumers to see the performance benefits without requiring direct access to the blade components themselves

Inventive Principle:
Principle #26Copying

2Loss of information

If the razor moves along an opaque surface, then the demonstration is easy to perform, but consumers cannot visually understand lubrication and moisturization performance

Engineering Contradiction:
Improveconsumer understanding of performance benefitsVSAvoiddemonstration method complexity
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The transparent surface serves as a visual medium that changes the optical properties of the demonstration setup. This allows consumers to see through the surface and observe the razor's interaction with lubrication and moisturization components, providing clear visual feedback about performance benefits while maintaining simple operation procedures

Inventive Principle:
Principle #32Color changes

3Loss of information

If components releasing lubrication and moisturization are hidden, then the razor design is simpler, but consumers cannot see the components that provide these benefits

Engineering Contradiction:
Improvevisibility of lubrication and moisturization componentsVSAvoiddemonstration apparatus structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The transparent demonstration surface fundamentally changes the visual accessibility of the razor components. By eliminating opacity, the surface allows direct observation of lubrication and moisturization components in action, providing consumers with clear visual information about what makes the razor effective without requiring additional transparent housing or complex disassembly mechanisms

Inventive Principle:
Principle #32Color changes

AI summary

A shaving demonstration method having a step of providing a first shaving razor with a shaving surface having at least one blade with a cutting edge. A transparent first surface is provided. The shaving surface the first shaving razor contacts the transparent first surface. Another step includes illustrating the shaving surface of the first shaving razor against the transparent first surface through a transparent second surface opposite the first surface. The first shaving razor is moved along the transparent first surface.
